how can i use new rss function in 1.5.31?Just copy and past in snews core file or...?

There's a little more involved than simply plugging in the new function... It's called a little differently in startup() for one. My advise is to upgrade. If your 1.5.31 is heavily modded, I feel your pain. I still haven't upgraded my site because I dread trying to make everything work with 1.6

i readed here that is no need to upgrate de mysql for -> 1.6 Update of Snews , onli overwrite de snews.php file.

Ok, I dead That and on Admin Login I have this error :Error

Wrong username and/or password and/or sum entered.

User is corect, pass is corect, sum is corect... but steal error.

I browsed the row password from mysql table settings and I changed the paswordt to test and I tryed to log in and the same error. I rewrite bach the 1.5 snews.php file and the login process goes without errors.

the above code should be added/altered in the Database using phpMyAdmin (or similar) to create a user=test and pass=test, just like the default sNews 1.6.After you have made the change, use test/test as the admin log-in.
